DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] A crane cab with a heat insulation structure, such as Figure 1-Figure 5 As shown, it includes a mounting plate 1, a cab frame 2, a sunshade glass 3, a first heat shield 4, a second heat shield 5 and a heat insulation structure 15. The top of the mounting plate 1 is fixedly connected to the cab frame 2, and the front and rear sides and the right side of the cab frame 2 are fixedly connected to the sunshade glass 3. The inside of the cab frame 2 is fixedly connected to the first heat shield 4, and the top of the cab frame 2 is fixedly connected to the second heat shield 5. The heat insulation structure 15 is used to block sunlight. The cab is installed on the crane through the mounting plate 1. When the crane is operating in a high temperature environment, the cab will be surrounded by high temperature air from the outside and directly exposed to sunlight. Most of the sunlight will be reflected by the sunshade glass 3, thereby reducing the heat in the room and preventing the entry of ultraviolet rays. By utilizing the heat insulation characteristics of the first heat shield 4 and the second heat shield 5, the high temperature from the outside can be blocked from entering the cab. The heat insulation structure 15 is activated to block sunlight, which can prevent direct sunlight, prevent the temperature in the cab from rising too fast, and reduce the loss of ultraviolet rays to the parts in the cab.

[0020] like Figure 1 and Figure 2As shown, the heat insulation structure 15 includes an electric push rod 151, a front sun visor 152, a side sun visor 153, a fixed shaft 154 and a guide rail 156. The electric push rod 151 is fixedly connected to the right side of the top of the second heat insulation board 5, the front sun visor 152 is fixedly connected to the moving rod of the electric push rod 151, the front sun visor 152 is slidably connected to the top of the second heat insulation board 5, the front sun visor 152 is fixedly connected to the fixed shaft 154 on both the front and rear sides of the top of the front sun visor 152, two guide rails 156 are fixedly connected to the top of the second heat insulation board 5, and two side sun visors 153 are slidably connected to the top of the second heat insulation board 5 through the guide rails 156. The two side sun visors 153 are symmetrically arranged front and back, and the right parts of the two side sun visors 153 are opened with inclined grooves 155, and the fixed shafts 154 are slidably connected in the corresponding inclined grooves 155. Initially, the front sun visor 152 and the side sun visor 153 are both folded at the top of the second heat insulation board 5. When the heat insulation structure 15 is needed to block the sunlight, because the inclined groove 155 is set on the side sun visor 153, and the fixed shaft 154 is fixedly connected to the two sides of the front sun visor 152, when the front sun visor 152 moves to the right, the two sun visors 153 are pushed away from each other by the two fixed shafts 154, and the electric push rod 151 is started to move the front sun visor 152 to the right, and the front sun visor 152 drives the two side sun visors 153 away from each other, so that the front sun visor 152 and the side sun visors 153 are both extended from the top of the second heat insulation board 5, which can completely block the ultraviolet rays. The driver needs to observe whether the crane operating environment can operate smoothly through the sunshade glass 3. At this time, the electric push rod 151 is started to move the front sun visor 152 to the left, and the front sun visor 152 drives the two side sun visors 153 to reset close to each other, and the front sun visor 152 and the side sun visor 153 are retracted. Since the front sun visor 152 and the side sun visor 153 protrude to the front side and the left and right sides at the top, when the driver needs to observe the crane lifting status upward, the sun visor will block part of the sight, which can be retracted and adjusted freely as needed. This ensures that the front sun visor 152 and the side sun visor 153 will not block the sight when observing the crane operating environment.

[0021] like Figure 1 , Figure 3 and Figure 4As shown, it also includes a heat-insulating frame 6 and a ventilation cylinder 7. A through hole is opened on the top of the driver's cab frame 2, and a ventilation cylinder 7 is fixedly connected in the through hole. The upper part of the ventilation cylinder 7 is fixedly connected to the heat-insulating frame 6. The ventilation cylinder 7 is opened with at least one ventilation hole, and the heat-insulating frame 6 is higher than the top of the driver's cab frame 2. By using the ventilation holes on the ventilation cylinder 7 to circulate air between the driver's cab and the outside world, fresh air can be provided to the driver's cab to improve the indoor air quality. The ventilation holes can allow the high-temperature air from the outside to slowly enter the driver's cab during air circulation, preventing the high-temperature air from the outside from rushing in quickly due to ventilation caused by opening windows and doors to increase the temperature in the driver's cab, and ensuring the heat insulation effect of the driver's cab while the air in the driver's cab is circulated.

[0022] like Figure 3 and Figure 4 As shown, it also includes a motor 8, a fan blade 9 and a first air expansion cylinder 10. The motor 8 is installed inside the air cylinder 7, and the fan blade 9 is installed on the output shaft of the motor 8. The first air expansion cylinder 10 is fixedly connected to the bottom of the air cylinder 7. When it is necessary to lower the temperature in the driver's room, the fan blade 9 is driven by the motor 8 to rotate at a high speed, and the outside air will be discharged into the driver's room from the first air expansion cylinder 10 through the air cylinder 7, so that the outside air and the indoor air can circulate quickly, and the indoor temperature can also be reduced. The first air expansion cylinder 10 can make the outside air enter the driver's room from the air cylinder 7 more gently, thereby improving the comfort of people in the driver's room when the crane is operating.

[0023] like Figure 3 and Figure 5 As shown, it also includes a ventilation frame 11 and a refrigerator 12. The ventilation tube 7 is fixedly connected to the middle of the ventilation frame 11, and the refrigerator 12 is installed on the top of the ventilation frame 11. At least one strip hole is opened on the ventilation frame 11. When the motor 8 is started, the refrigerator 12 is started. When the fan blade 9 rotates, the cold air generated by the refrigerator 12 is discharged downward into the driver's cab through the strip holes on the ventilation frame 11, so that the air temperature in the driver's cab is further reduced. When the driver's cab is idle, the refrigerator 12 is turned off. Before entering the driver's cab, the motor 8 and the refrigerator 12 are turned on to cool down the driver's cab in advance, so that people are more comfortable during lifting operations.

[0024] like Figure 3 and Figure 5As shown, it also includes an air outlet pipe 13 and a second air expansion cylinder 14. Two air outlet pipes 13 are fixedly connected to the front and rear sides of the bottom of the air permeable frame 11. The air outlet pipes 13 are all located in the second heat insulation board 5. The exhaust ends of the air outlet pipes 13 pass through the top of the driver's cab frame 2. The exhaust ends of the air outlet pipes 13 are fixedly connected to the second air expansion cylinder 14. When the refrigerator 12 is started to cool down the driver's cab, the cold air generated by the refrigerator 12 will also be discharged into the driver's cab from the air outlet pipe 13, and discharged into the position far away from the air permeable cylinder 7 in the driver's cab through the air outlet pipe 13, which can fill the entire room with cold air and cool down the driver's cab faster. After the crane operation is completed, the refrigerator 12 is turned off to avoid unnecessary waste of resources. The second air expansion cylinder 14 can diffuse the cold air and accelerate the diffusion of the cold air in the driver's cab.
